All you have to do is disconnect a small black vacuum tube that connects to a valve that is connected to the tailpipe about 6 inches from the tip. Just look under the car at the passenger tailpipe and it will be very easy to see. You then put a screw or golf tee into the tubing and I put some black electrical tape around it to keep it in and covered the valve nipple with tape to keep water out. Takes about 2 minutes and makes a noticeable difference.

Thanks Tim...
Will try this technique and get back to you. I had a 135, and did the golf tee trick and it was a noticeable difference. Just didn't think that our cars had the vaccum hose as well....GOOD TO KNOW
